FRED 'C. DE VAiLLANT, OF EARLVILLE, NEW YORK.

HAND-PROPELLED DUST-COLLECTOR.

Specification of Letters Patent. Patented July 26, 1910.

Application filed January 27, 1910. Serial No. 640,403.

To all whom it may concern:

Be it known that I, Fnno C. DE VALLANT, a citizen of the United States, residing at Earlville, in the county of Madison and State of New York, have invented certain new and useful Improvements in Hand- Propelled Dust-Collectors, of which the fol lowing is a specification.

This invention relates to dust collectors, and pertains especially to the class of transportable hand operated pneumatic dust collectors.

The object of the invention is to provide an improved, simplified, roller or truck de vice, adapted to be propelled by hand over a floor or carpet dunn simultaneous working by hand of a bellows carried by the truck, for collecting dust into a can or similar vessel carried by the truck and connected with the bellows. I

A further object of the invention is to provide a truck for dust collectors, with a nozzle frame carried by and loosely mounted on the truck axle so that the latter may have vertical pivot movement in the frame, a nozzle stem rigid with the frame so as to be turned laterally with the truck and at the same time adjust itself to the floor by reason of said vertical movement of the axle.

A still further object of the invention is to provide novel and peculiar connect-ions between the. dust bag and dust can cover and between the latter and the can to per-' mit of the removal of the cover and the bag together from the can without uncovering the bag.

Other objects, advantages and improved results are attainable through and by the special arrangement and construction of the various parts of the device, hereinafter to be fully described.

In the accompanying drawings forming part of this application: Figure 1 is a side elevation. Fig. 2 is a top view. Fig. 3 is an enlarged sectional view of the dusty can. Fig. 4 is a perspective view of the nozzle frame and axle partly broken away. Fig. 5 is a detail elevation of the can cover showing the dust bag suspended therefrom and covered thereby. Fig. 6 is an edge or top view of the clamping ring open. Fig. 7 1s The same reference numerals denote the same parts throughout the'several views of the drawin s. r e

The truer wheels 1 are mounted on an axle 2, journaled in a truck frame 3, from which extends a hand rod 4 for propelling the truck. Such rod having a floor rest or support has attached to it a bellows 6, hereinafter more particularly referred to.

In order to provide means whereby the nozzle may be adjusted laterally and lon itudinally, and yet be turnable with t e truck in its various propelled directions, I provide a nozzle supporting frame 7, havin the stem 8 of a nozzle 9 rigidly connected thereto by an arm 10 central of the'frame, and at the intersection of the frame and the stem there is a depending post or rojection 11, pivoted to a collar 12 in which the axle 2 revolves. Such collar and pivot connection permits the frame to be swung on the axle so as to adjust the nozzle vertically during the propelling of the truck in a dust cleaning operation.

The axle extends from the collar 12 through slots 13in the depending ends of the framefor the purpose of limiting the relative vertical movement of the frame and the axle. Said frame 7 extends lengthwise the axle and is pivoted above the center thereof, so

And said frame supports andv that the axle 'and its wheels may have freewhereby the nozzle may always be in workingcontact with the carpet or floor irrespective of the position of the truck wheels.

A dust can 14 is mounted on and secured to the frame 7, preferably forward of the I axle 2, and has a cap or cover 15 detachably secured to the can by means of thumbscrews 16 extendin through peripheral flanges of the cap an can, The cap or cover 15 has a double elbow pipe 17,-one end of which projects downwardly within the cover and the other end projects downwardly outside the cover and is connected with the nozzle stem 8 by a hose or pipe 18.

One of the essential features of novelty pended in the can and advanta e of this invention is in connecting the ust bag to the can cover so that such cover may not be removed from the stuck or bag in removing the cover and the bag from the can. The sack or bag 19 is fixed to an open spring ring or band 20, having over-lapping ends adapted to be clamped around a neck or depending flan e 21 of the can cap or cover 15 and the a is susby placing t e cover thereon and in removing or replacing the cover the elbow pipe is detached and attached to its hose pipe 18, so that the cover, the elbow pipe and the dust sack or bag is removable from the can intact, thereby keeping the dust ba closed after its removal. The device for c amping the spring hand or ring 20 to the cover neck 21, consists of a lever 22 pivoted to one end of the band, and a link 23 pivoted to the band adjacent its other end andfulcrumed to the lever at 24. It is obvious that by moving the lever 22 the band may be opened and closed, as clearly shown in Figs. 6 and 7. The can cover is fitted with a rubber gasket 15, for making an air-tight joint between the cover and the can.

The bellows 6 is connected to the can by a pipe 25, and is operated by means of a crankshaft 26 having a balance-wheel 27, and operated by a beveled gear and pinion 30 connected to a hand crank 28 by a" shaft 29.

It will be seen that the parts are arranged to balance on the truck wheels, so as to assist the pivot movement hereinbefore described.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. In a hand propelled dust collector, the combination with a truck including a wheeled axle, a dust can, and a suction creating means mounted on the truck and connected with the can, of a frame supporting the can and having slotted ends through which the ends of the axle work, a pivot connection between the axle and the frame,

I and a floor nozzle suspended from the frame 1n communication with the can.

2. In a dust collector, the combination, with a truck, including a wheeled axle, suction creating means carried by the truck, a dust can in connection with such means, and a floor nozzle connected with the can, of a frame supporting the can and having the floor nozzle rigi ly connected thereto, and means for ivotall connecting the said frame with t e truc axle.

3. In a pneumatic dust collector, the combination, with a dust can having a pump and a floor nozzle connected therewith, and a truck supporting the can, of a frame to which the nozzle is fixed, and means connecting the truck axle with the frame so as to permit vertical pivot movement of the axle 1n the frame without imparting such movement to the nozzle.

4. In a pneumatic dust collector, the combination, with a dust can, a pump connected with the can, a floor nozzle, means connecting the nozzle with the can, and a wheeled axle, of a frame supporting the can and having an arm from which the nozzle depends, and means connecting the axle with the frame so that the axle may have vertical movement in the frame.

5. The combination, with a truck including a wheeled axle for supfporting and prope ling a dust collector, o a frame havin a post to which the axle is rotatably and pivotally connected, the ends of the frame having slots through which the axle extends for limiting its pivot movement, a pump on the truck and a floor nozzle in communication with the pump and projecting from the frame and adapted to adjust itse to such pivot movement of the axle.

f relative In witness whereof I hereunto set my.

hand in the presence of two witnesses.
